To all whom it may concern:

Be it known that we, HENRY J. EBER and CHARLES T. LENTZ, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in Lamps, of which the following is a specification.

The objects of this invention are to provide a lamp with a smooth regular outer surface devoid of projections; to thus enable the lamp to be dusted and polished with minimum labor and expenditure of time; to thus provide a lamp especially adapted for automobiles and other vehicles; to obtain a simple and inexpensive con! struction for such a lamp, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several gures, Figure 1 is a front elevation of our improved lamp; Fig. 2 is a side elevation of the same, looking in the direction indicated by the single arrow in Fig. 1; Fig. 3 is a side elevation looking in the direction indicated by the double arrow in Fig. 1; Fig. 4 is a plan view with the top or cover removed and the front door ajar; Fig. 5 is a view of the under side of said top or cover, as removed; Fig. 6 is a view of the lamp from beneath, with the lamp proper removed; Fig. 7 is a side elevation of said lamp proper as removed; Fig. 8 is a detail section taken horizontally through the catch for the front door of the lamp, as on line 8 of Fig. 1; Fig. 9 is a detail section taken vertically through one of the' feet for holding the removable top on the lamp, as at line 9 of Fig. 4; Fig. 10 is an edge view of one of the resilient detents for holding the lamp proper in position in the lamp case, looking in the direction indicated by the arrow in Fig. 6, and Fig. 11 is a section on line 11 of Fig. 4, showing the provision made for turning the wick spindle.

In said drawings, 10 indicates the lamp casing, made globular or spherical in form, with a smooth exterior surface and chambered or hollowed interiorly. At the back of said casing is an exterior supporting stem 11 projecting radially from the surface and having a transverse hole 12 to receive the arm of a bracket (not shown) and a set screw 13 to clamp against said arm as is common.

At the front of the lamp casing 10 is a round aperture 14 having a frame 15 to which is hinged the frame 16 of a door 17 as at 18, said door consisting of glass 19 set in said frame 16. The frame 15 has opposite the hinge 18 an interior projection 20, and the door frame 16 is provided with a spring catch 21 to hook over said projection 20 and hold the door closed. For releasing said catch 21, a lever 22 is pivoted upon the casing frame 15; to engage at one end the catch, and having at its other end a pivotal pressure piece 23 normally projecting into a hole 24 in the casing 10 so that its outerend is flush with the outer surface of the casing. By pressing said piece 23 with the finger nail, the door 17 is positively thrown open, as shown in Fig. 4.

One side'of the lamp casing 10 we have shown entire and unbroken, but at the opposite side we have illustrated a circular aperture 25 in which is set a frame 26 holding a concave-convex glass 27, which would be red in color, by the usual rules. The plane of this aperture 25, and the plane of the frame 15 for the door 17, are both vertical or perpendicular to the central plane of the lamp casing 10 which passes through its supporting stem 11. The bottom of the casing 10 is cut off horizontally or parallel to the said central plane of the lamp casing which passes through the supporting stem 11, providing an aperture 28 in which is xed a ring 29 having interior flanges 30 projecting radially into said aperture. These flanges 30 have each a keyhole slot 31, and beneath at least one of them is a resilient detent 32 comprising a leaf spring riveted at its end over the narrow end of the slot to the ange, as at 33. The other end of the spring 32 is free and inclined away from the flange, while between said ends of the leaf spring is a recess 34- beneath the narrow portion of the slot. lamp proper, as shown in Fig. 7, is adapted to be inserted from beneath the lamp casing into said bottom aperture 28, and this lamp proper has a base 35 adapted at the fiat edges of its upper side to t the aperture 28, and rounded at its lower side to conform to the spherical contour of the lamp casing. The said upper flat edges have upwardly projecting posts 36 with heads 37` to enter Vvthelargev endsv ofthe key` hole slots 31 and reduced necks to enter the narrow ends of saidVV slots whenl the basef'35 Y is slightly rotated.` By the means described, therefore, the lamp proper can be detach-` ably secured to the lamp casing, and prefer'- ably said posts 36 are long` enough sothat a draft space 38V is left between the base and ring 29. The head 87 of one ofthe posts 36, when turned toward vthe narrow end of its keyhole slotel, .pressesagainst the resilientrdetent 32 and ridesoverthe free 'end of the. same into the recess ;34,alc' oveA described, and `holds said'. vpost and there- !fore the lamp proper against inadvertent cmay. be inserted from outside `to clutch-,the-

wickspindle, andraise or lower. thel wick as desired.

The. topA 43 `of; the lamp, casing cuty off Ona horizontal plane, and a ring`44 fixed in the aperture with. an interior annular flange 45 with keyhole slots 46 `and an up-4 turned inner edge.V 47 ,las shown. Theytop 43 also yhas headedposts48 adaptedito enter saidi s'lotsand lock therein. upon slightly turning 'said' top, said posts being i long enough-to hold the top slightly away from 'the casing body andafford an upper-draft space 49 for. the lamp proper, as shown in Fig. 2.

It will be understoodthat the front door 17,the side 'glass 19, the base 35Vof the,

lamp proper, and the topy 43are all exteri* orly rounded or curved in the same spherical surface as the casing body, and furthermore -the frames and rings'by which said'removable partsVA are mounted project Hush with said. sphericalsurface andnot beyond the same. A: complete spherical outer. surface, with the exception of the supporting stem 11,.is thus provided by our improved construction of lamp,and therefore the said Vsurface can be easily and Y conveniently cleanedor polished. greatsaving of time andflabor is thus'ieft'ected, as well'as great neatness of appearance, and yet without sacrificing the constructionalconveniences of' rlamps of other shapes. i A

' I-Iaving thusv described the.` invention,`

what we claim is:
